Blockbench vs PMCSkin3D

Blockbench is a free, open-source editor for making low-poly 3D models. Its tools support cuboid and mesh modeling, and users can create, edit, and paint textures in the program. Blockbench can generate a model's UV map and template, and connect to an external image editor or pixel-art program. For animation, it supports rigging, position, rotation, and scale keyframes, along with a graph editor. The built-in plugin store offers extensions such as tools, export formats, and model generators; users can also create plugins. Blockbench is available as a web app and on Windows, macOS, Linux, iOS, and Android. The project is licensed under the GPL. Its privacy policy says the software does not knowingly collect personally identifiable data, though it may collect anonymized usage information such as installation count. Local storage and cookies can remember preferences on a user's device. When users choose Model Sharing, model data is stored for the duration they select, and they can request earlier removal.

PMCSkin3D is a browser-based editor for creating and adjusting Minecraft skins. It lets you paint on a 3D model and inspect the skin on that model as you work. The editor supports HD skins and both the standard and Slim (Alex) models. You can load a skin by username, then pose and animate the model to view it in different positions. These tools keep the focus on making changes to a skin and seeing how it appears on a model. PMCSkin3D runs in a browser and is free to use, with a free plan. Its website is the Planet Minecraft skin editor page. No desktop or mobile app is listed; the stated platform is the browser. For people who want to work on Minecraft skins without paying, its listed features include model painting, HD skin support, model selection, username loading, posing, and animation.
